Why is my uvmap created using uvproject modifier scaled up?
I'm guessing the reason you have this problem is that:


The original object named Plane in the outliner has been scaled up by 5 from its original size. 
The UV's of this Plane needs to be rotated by 90°.


The quickest way to fix this is to work with the Empty


Select the Empty.
Scale it up by a factor of 5. ( S  5 Enter )
Rotate along Z axis 90°. ( R Z 90° Enter )


The result of doing this should be as in the screen shot below:
